ODK Aggregate server backup

What is the problem? Please be detailed.
I am now running ODK aggregate server v 2.0 via Digital Ocean by following the documentation provided. My question is, is it possible to have a kind of a redundant server or a backup server so that in case when something goes wrong with the primary, will have a backup ready?

I am asking this because previously, I had an ODK Aggregate server in google, but then I encountered problems extracting data, so I moved to the new version as stated above.

What ODK tool and version are you using? And on what device and operating system version?

What steps can we take to reproduce the problem?

What you have you tried to fix the problem?

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.

It's always a good idea to have backups!

Digital Ocean has automated weekly backups that you can enable. For more frequent backups, see https://docs.opendatakit.org/aggregate-backup.
